8-27.

At 3:25pm, two trains left Kalamazoo, Michigan. One train traveled westward at a constant rate of 82 miles per hour, while the other traveled eastward at a constant rate of 66 miles per hour. If they are now 111 miles apart, what time is it now? Write and solve an equation (or system of equations) to answer this question. Homework Help ✎

Distance = (rate)(time)
Write a distance equation for each train.

If the trains are 111 miles apart, then their 'total distance' is 111. Use this to write an equation.

82t + 66t = 111
Note: The solution to this equation is not the answer to the question asked in the problem.
